https://devzone.nordicsemi.com/f/nordic-q-a/54663/disable-pa-lna-after-connectionI use a PA/LNA dur9ing advertising but would like to disable it during connection. I use the sd_ble_opt_set API which works fine to enable GPIO toggling. However to disable after a connection I used the code recommended in this post https://devzone.nordicsemien-USTelligent Community 13Thu, 21 Nov 2019 20:56:05 GMThttps://devzone.nordicsemi.com/thread/221432?ContentTypeID=1Thu, 21 Nov 2019 20:56:05 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8ac16fcd-6315-466b-8754-97e49f7ed4cbKenneth<p>I believe there is a&nbsp;ble_radio_notification.c/h file in the nRF5 SDK that can be used, make sure to call it before you start to advertise.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/221426?ContentTypeID=1Thu, 21 Nov 2019 20:04:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0aa662d0-a338-4ee4-88a6-55cc3d0629feDave_couling<p>Could I subscribe to radio notifications to assure this occurs between radio events?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/221309?ContentTypeID=1Thu, 21 Nov 2019 12:13:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:511be932-13a5-4abd-b07d-ca6973a74597Kenneth<p>It is not possible to disable the lna/pa pins while in a connection, from the api documentation it says: &quot;Setting this option while the radio is in use (i.e. any of the roles are active) may have undefined consequences&nbsp;and must be avoided by the application.&quot;</p> <p>Kenneth</p><div style="clear:both;"></div>
